FRANK LESLIE WVILLIAMS, OF NASHVILLE, TENNESSEE.

SHAKER OR MIXER.

SPECIFICATION forming part of Letters Patent No. 723,796, dated March24, 1903.

Application filed January 19, 1903. Serial No. 139,637. (No model.)

To all whom it may concern:

Be it known that I, FRANK LESLIE WIL- LIAMS, a citizen of the UnitedStates, and a resident of Nashville, Davidson county, State ofTennessee, have invented certain now and useful Improvements in Shakersor Mixers, of which the following is a specification.

My invention relates to improvements in shakers or mixers particularlyapplicable for use in mixing beveragesas, for example, in shakingliquids combined with a cooling or heating agent to impart an abnormaltemperature thereto and especially wherein ice is employed for impartinga cold temperature to the liquid; and my primary object is to provide animproved shaker or mixer which can be readily manipulated withoutchilling the hands or subjecting them to uncomfortable temperature andone. in which when lumps of ice are used the outside will not becomebattered or indented by violent contact with such solid particles andfinally to provide a shaker or mixer which will more efficiently performthe service intended by reason of the comfort in handling, therebyinducing the manipulator to more thoroughly perform the mixing operationthan heretofore.

With these objects in view my invention consists in the novelconstruction of shaker and in the details thereof, as hereinafterdescribed with reference to the accompanying drawings, and moreparticularly pointed out in the claim.

In the drawings, Figure 1 is a longitudinal vertical section of myimproved shaker; and Fig, 2 is a transverse section thereof on the line2 2, Fig. 1.

Referring to the drawings, in which the same reference characters relateto the same or corresponding parts in both views, myimproved shaker ormixer consists of an outer vessel 1, preferably of frusto-conoidalshape, the bottom of which is provided with perforations 2 for thecirculation of air between the outer and inner vessels. Within thisouter vessel is secured by brazing, soldering, or other suitable means asimilarly-shaped inner vessel 3, having an imperforate bottom 5 andsmaller in size than the vessel 1, thereby providing a space 4 aroundits sides and bottom of sufficient volume to permit the access, of thedesired quantity of air of the temperature of the surroundingatmosphere, which will be of a sufficiently high temperawhen hotbeverages are mixed.

ture to keep the outer vessel at a comfortable temperature, at leastonewhich can be easily borne by the hands. This body of air which entersthrough the perforations 2 constitutes an efficient non-conductingmedium, which prevents the transmission of abnormal tern? perature fromthe inner vessel to the hands of the manipulator as the latter graspsthe outer vessel. When mixing cold beverages, it will be seen that thehands are prevented from becoming chilled, because the outside willalways remain sufficiently warm, and thus bartenders and others areprotected from exposure to rheumatism and other diseases arising fromsudden chills, and similarly protection is afforded against very hottemperatures, where the liquid in the mixing vessel 3 is very hot, asmay be the case Moreover, the outer vessel never becomes battered bycontact of lumps of ice against its side, he-

cause these come in contact with the inner vessel only, and thereby theappearance of the device is maintained and the manipulator will be morelikely to give the necessary amount of time to the shaking, thus notonly more thoroughly mixing the ingredients, but producing a colderbeverage and giving greater satisfaction to the patrons. Finally,condensation of moisture will take place, not on the walls of thereceptacle in contact with the hands, as heretofore, but upon the outerperiphery of the inner vessel and the inner periphery of the outervessel, and such condensed liquid will flow downwardly and outwardlythrough the perforated outer bottom.

I claim as my invention As a new article of manufacture, thehereindescribed shaker or mixer, consisting of an outer vessel adaptedto be grasped by the hands and having a perforated bottom for the freecirculation of air, an inner vessel having an imperforate bottom andsupported within said outer vessel and providing a nonconducting spacearound the sides and bottom of said inner vessel, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FRANK LESLIE WILLIAMS.
